WMD bolt-and-carrier set is precisely machined from high-grade steel alloy to government M16 specs, then given WMD's proprietary NiB-X nickel boron coating that results in a super-smooth, harder-than-chrome surface. NiB-X reduces friction to the bare minimum and is impervious to corrosion and abrasion. Drop in for AR15 / M16 rifles.

Amazing bolt carrier group. I have not shot with it yet but wanted to post a review and say that Red Barn Armory has amazing customer service and they are great to work with. Thanks for the awesome BCG at an amazing price!

Carrier looks great. The NiB finish is done very well and fast shipping. What more can you ask for?
